Implement a compiler plugin to aid code generation about inline-java HOT 2 CLOSED

Work in progress branches

master...fd/bytecode-table
This has an implementation of a bytecode table. The static pointer table is not used anymore to embed java bytecode in executables. The main problem with it is that if the programmer forgets to pass -fplugin=Language.Java.Inline.Plugin to ghc, it will get NoClassDefFoundException at runtime. This is going to be solved by https://ghc.haskell.org/trac/ghc/ticket/13608#comment:21. While that is not implemented, the situation will improve when the generation of Java happens in the plugin, because in that case we can have the code produce a better runtime error when the quasiquotation annotations are not removed.

master...fd/plugin-types
This is not a finished feature but some hacking on the inline-java plugin to show how the program can be annotated with a function that carries the types that the plugin will need to generate the java code. It features a function to convert TH names into Core names, and a Core pass to collect the occurrences of the function used to annotate the quasiquotations.
